SPECIFICATION forming part of Letters Patent No. 271,075, dated January 23, 1883.

i Application filed Septomber20,1878; y

1'0 all whom It may concern Be it known that I, LEMUEL POPE JENKS, a citizen of the United States, and a resident of the city of Boston, in the county of Suolk and State ofMassachusetts, have invented a new and Improved Carpet-Lining and Paolo ing for Glassware, ofwhich the following is a specification.-

The nature of my invention consists ofa carpet-lining formed from a sheet of paper, which is stretched by passing it between the peculiarlyshaped rollers hereinafter described, or byother mode hereinafter adverted to 5 and the object is to furnish an article to place under iioor-carpets to diminish the Wear of the same, furnish a place of deposit for the dust, and also an easy tread for the feet, and, further, to furnish an elastic packing for bottles, crockery, and other easily-frangible substances.

In t-he drawings, Figure l represents a view from above of my carpet-lining. Fig. 2 is a vertical sectional view of the same.

The device shown in the drawings may be described as 'simply a sheet of paper, with a series of cavities, circular in horizontal section and nearly hemispherical in vertical section, established in the body of the paperby means of passing it between two surfaces, (which may be either plane. or cylindrical,) one of which bears the iigure. in cameo and the other in intaglio. The paper, being submitted to a passage between these two surfaces, is stretched, its bers being drawn apart, to the greater degree, ofcourse, at the top or apex of the cameo projections, and, this being done while the paper is wet, the complete separation or breakage of the stretched parts is infrequent and practically works no detriment. I do not couline myself to cavities presenting a circular shape to aview from above; butsometimes produce a scroll-like form, or one which is lozen geshaped or square, or of the well-known figure commonly seen in Cashmere shawls, the main object being by stretching of the fibers, primarily disposed by the paper-making machine so as to present a plane surface, to form a cavity on one side of the paper, and a corresponding projection on the other side. The device I use for effecting this stretchin g, denting, or em, bossing is preferabl ya pair of rollers, with their cylindrical surfaces bearing respectively, one,

a number of projecting bosses or studs of the desired shape, and the other corresponding cavities, the former, in successive rotation ot' the rollers, entering into the latter, the paper being fed between them. I take the sheet, dampened or wetted as it is, when coming from the paper-machine--say the well-known Fourdrinier machine. Thus, as the paper comes from the forming-machine, it passes continuously between my rollers, and is then dried in the usual manner. Another way which I practice to effect the denting or embossing is to use metallic or other slabs or plates, with the required cameo or intaglio, and feed the paper intermittently between the two surfaces, a direct upward and downward pressure communicated to the plates, respectively, effecting the desired embossment. When the denting is effected the dent presents in vertical section the form of an arch, the support of the arch being the remaining non-dented plane: surface of the paper, and each point of support being at a short dist-ance from the center of the dent. This arch being formed by the stretching apart of the mass of fibers of the paper at that point, by which the be-rs are caused to reach halt' round the periphery of a circle, (instead of across the diameter of the same,) any pressure (as by the foot, when the lining is in use) downward upon the arch or the dentsimply bends the iibers momentarily, but cannot restore them to their original straight condition. Thus the dents remain and the springiness of the carpet-lining continues till the paper is worn out. The stretched embossed paper has a certain nat-ive resilience; but 1 propose to add to this, by treating (either on one side only, or on both, in the case to saturation) the paper with a iuid composition, which, hardening, gives elasticity. For this purpose Im use preferably a'.

mixture of glue and glycerine, in the proportion, preferably, of one part of glycerine to twenty parts, by. weight, of glue; but I do not confine myself to these e'xact proportions of these ingredients. This is brought, by the addition of Water and by heating, to a point ot', say, 660 Baume at a temperature of 150O Fahr enheit. I apply this coating sometimes to the plane-surface dry paper and then effect my denting, subsequently expelling by evaporation all of the mixture which is expellable by ICO heat.

process of embossing or denting by rollers, I place my intaglio or hollow-cavity roller beneath, and cause it to rotate partially immersed in a tank, reservoir, Vat, or trough filled with elastic composition, keeping the mixture heated by steam-pipes or inother convenient manner. The roller-cavites then, charged with the composition, part with it to the paper, or that side of the same which when finished presents the projections or bosses to view, and the coating of composition thus given is sufficient. I sometimes, however, pass the paper, Wet or dry, by means of plane cylindrical rollers, entirely under the surface ot' the liquid composition, thus coating both sides, in this case eX- pelling any supertluity by compression between another pair of rollers, and sometimes mix the glue and the glycerinc with the paperpulp in the paper-engine. I do not coniine myself in the use of this elastic composition solely to my own dented paper, but apply it to any corrugated paper carpet-lining or bottlc-packing to communicate a desired resilience. Nor do I confine myself solely to the composition named for giving elasticity to carpet-lining of paper, as I sometimes use a coating of india-rubber or other composition, ythe condition being that the same shall be primarily a liquid and subsequently hardened after Adverting to the' previously-describedV application. I sometimes paste, cement, or glue to one or both sides of my article a thinner sheet of paper, but I do not consider it essential. In using my article I prefer to have the intaglio side upward.

The kind ot' paper which I use is preferably what is called soft77 by the paper-makers, and an admiXture of short wooden fibers or shoddy at the same time cheape'ns the article and facilitates the necessary stretching.

I do not claim an article made by bending o corrugatin g the body of the paper, or one made by com pressing the same so as to present ridges ,or other shapes.

glycerine in the proportions specied, all sul stantially as described.
